Does anyone know what kind of tool to use to purge the old fluid out of the lines when you are putting one of these new actuators on, Is there some type of pump to screw on the line that disconnects from the actuator to put pressure on the line . mine had the rusty fluid/water in the resevoir so hopefully the wheel cylinders are not froze up

I got the black DuPont MasterCraft color for mine at NCS (National Coatings and Supplies). $20 to have it mixed and put in a spray can. It took two cans to get a nice coat. So $40 plus another $15 for a can of primer. Turned out great and the color is an exact match.

Yes, mine is black. E-mailed MasterCraft and got the DuPont paint code directly from them.
My last MasterCraft, '92 ProStar, had a UFP and twenty years later I was still able to get parts. Happy to be rid of the Reliable.
